쿠...sal: [컴][안드로이드] notification 예제

notification 삭제, notification 사용법, notification 활용, notification update, notification creation, download notification, 다운로드 할 때 notification 에 표시

mBuilder.build() 가 Notification()(NotificationCompat) object 를 return 한다. notification 에서 사용할 data 를 만들어서 notificationManager 에게 준다고 보면 되겠다.

NotificationTestActivity.java

public class NotificationTestActivity extends Activity {

  public final static String TAG = "Demo";

// private Builder mNotifyBuilder;
  private NotificationManager mNotificationManager;
  private NotificationCompat.Builder mNotifyBuilder =
